Woodscrews - Pozidrive Countersunk Twinthread

Twinthread woodscrews are a traditional woodscrew that gives rapid installation into softwoods. They are also an ideal choice for use with a plastic wall plug when fixing into masonry.


A twinthread screw has, as the name suggests, a pair of threads that run along the screw body. The pitch of a twinthread screw (the distance between the threads) is usually greater than that of a single thread screw.

The result of this is that installation is faster with a twinthread screw.
Twinthread screws are easier to get started and are generally easier to drive into position than single thread screws.

When it comes to the sizing of woodscrews it is still very common to find measurements in both metric and imperial. The diameter of a wood screw is either given in a gauge (imperial), or in millimeters (metric). With the imperial gauge, a number is used, i.e. 8 gauge. A larger gauge number means a larger diameter. Screw gauge numbers actually correspond to a particular fraction of an inch in imperial measurements.

Woodscrew lengths are also often shown in either metric or imperial sizes, or sometimes both.

A countersunk head is usually used when no part of the fastener head is required to be protruding above the level of the substrate. Countersunk heads can also be recessed and filled over if a hidden fixing is required. Usually abbreviated to CSK.

Pozidrive heads have been designed to ensure that the screwdriver will not slip under torque. This makes them ideal for use with impact drivers and other power tools.

The best way to identify a Pozidrive head is by the diagonal engraved lines between the four points of the cross head.
